Featuring super smooth CeramicSpeed grade 3 Silicon Nitride balls, these bearings are precisely matched within microns to hardened steel raceways with an ultra-smooth polished groove. The reinforced polyamide cage ensures the balls remain securely in place, while the exclusive low viscosity CeramicSpeed “Blue Grease” minimizes friction and extends bearing life.\u003c\/p\u003e\n\n\u003cp\u003eDesigned for versatility, this bearing suits various cycling disciplines including Road, TT, Triathlon, Track, Cyclocross, and MTB. Its non-contact seals effectively keep dirt and moisture out, maintaining optimal performance over time. The superior engineering of CeramicSpeed Balls—400% smoother, 128% harder, and 58% lighter than standard steel bearings—translates to better power transfer and enhanced durability.\u003c\/p\u003e\n\n\u003cp\u003eEach bearing undergoes rigorous quality control with four manual inspections during assembly, ensuring perfect matching of components. Compared to other ceramic balls on the market, CeramicSpeed Balls are 15% harder, handle 99% higher loads, and offer 100% smoother operation, making the Single Bearing R8 an essential upgrade for serious cyclists seeking efficiency and reliability.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eReducing friction for smoother, more efficient pedaling\u003c\/li\u003e\n  \u003cli\u003eImproving power transfer to maximize cycling performance\u003c\/li\u003e\n  \u003cli\u003eExtending bearing life with advanced materials and lubrication\u003c\/li\u003e\n  \u003cli\u003ePerforming reliably across multiple cycling disciplines\u003c\/li\u003e\n  \u003cli\u003eResisting dirt and moisture with non-contact sealing technology\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat It’s NOT Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eApplications requiring bearing sizes outside the specified dimensions\u003c\/li\u003e\n  \u003cli\u003eHeavy machinery or non-cycling uses\u003c\/li\u003e\n  \u003cli\u003eEnvironments with extreme contamination beyond typical cycling conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAre these bearings compatible with all bike hubs?\u003c\/strong\u003e\u003cbr\u003eThe CeramicSpeed Single Bearing R8 fits hubs designed for a bearing with an inner diameter of 12.7 mm, outer diameter of 28.575 mm, and width of 7.938 mm.
